I had a problem with hard start when the engine was warm. I replaced the Actuator which did no good other than lighten my wallet. On the advise of Jerry Rine (top drawer DeLorean mechanic - Columbus, Ohio) I had a Volvo dealer replace the checkvalve in the fuel pump (it was a new pump, too). The car has run perfect ever since. Cost was most reasonable $30.00. I had the fuel pump area opened for them! Marvin drinkware@xxxx
